The leading company in power energy industry of Mongolia

A powerful channel to distribute development

Brief introduction

“Altai Trest” LLC was first established on May 28, 1993. “Altai Trest” LLC is leading the field of energy with its rich experience accumulated, enormous works completed, professional workforce and material base in the field. Moreover, the company has been introducing new advanced technology in the field. It has been working in the wide range of development  around Mongolia.

“Altai Trest” LLC, which has been operating under New Progress Group Since 2002, carried out 16% of the construction work in the energy construction sector in 2006. In 2007 to 2008 the year of Great Development Project, 14.5% of the largest construction work in the energy sector was completed by our company alone. Also 1000-kilometer-long overhead power line with substations was built.

In recent years, in the field of energy construction, we have been working in the country’s infrastructure sector by performing the construction of overhead transmission lines and substations in the due time and with high quality.

OUR IDENTITY

DETAILED PLAN AND ASSESSMENT

When carrying out power construction work, the work volume and budget of the object is carefully studied, and a graphic plan is drawn up based on detailed assessment of manpower, machinery, time to be spent, and materials.

PRIOR PREPARATION:

In addition to carefully carrying out technical maintenance of the machines that will work at the site, preparing spare parts and creating an opportunity to work without interruption, the workers’ accommodation, food, and household supplies are fully prepared at the site to create a condition for the quality execution of the construction work in a short time.

MANAGEMENT CONTROL:

We provide professional management of the work of the brigade working at the site, check safety operations and build a professional engineering technical team to monitor and guide the work process.

RELIABLE CONTACTS:

We have reliable domestic and foreign partners who supply materials and equipment which are used in all types of power transmission lines and substations.

OWN MANUFACTURER:

As we produce the reinforced concrete supports and reinforced concrete structures necessary for the construction of overhead transmission lines and substations, we can reduce the cost of raw materials and keep the cost of the work budget low.

OCCUPATIONAL SAFETY:

By strictly implementing the technological procedures in any work, we work without any types of accidents and fatality. In addition to maintaining technical and safety journals at each facility, “Labor protection-Safety techniques-Hygiene”, professional and labor law training are conducted annually among our employees and mechanics and quality and professional, labor protection-safe operation level examinations are conducts to confirms their understanding.

OUR DEVELOPMENT WORK

We started a new page in the history of the development of energy sector of Mongolia by building and handing over a 220 kV high-voltage two-circuit overhead transmission line with iron supports (101 kilometers long from the border of Mongolia to the center of Uvs province) at high rating quality based on its own construction, production base, engineers and professional workers without any assistance of foreign experts for the first time in Mongolia.

With more than 20 years of experience in the field of energy construction, Altai Trest LLC, the leading company in the field, has built about 3100 km long overhead transmission lines and more than 80 substations, established the integrated power system of the western region and  connected more than 60 soums of provinces such as Uvs, Bayan-Ulgii, Khovd, Khuvsgul, Uvurkhangai, Gobi-Altai, Bayankhongor, Khentii and Dornod to the integrated power system of the region with its effort to establish Mongolia’s integrated power system and expand the scope of it.
